# Where to find others with Prusa3D i3m3s/MMU2s printer?

I don't want to ask off-topic and opinion questions here, but I would like to find a cadre of others dialing in their devices. Any ideas?

• Try Facebook groups. For example: facebook.com/groups/prusacommunity – Mick Apr 22 '19 at 21:18
• HI, I migrated the question to meta, I hope that you understand why. :-) BTW, What do you mean by dialing in their devices exactly? Do you mean comparing their printers and posting pix? Or something else? @Starwind has a (large?) Facebook group, he might know more...? I don't have a Facebook account (left it years ago) so I don't know anything about that... – Greenonline Apr 22 '19 at 22:03
• I thought I had written it on meta. I wonder what I did wrong? It is totally not a main group question. – cmm Apr 22 '19 at 22:46
• @greenline I'm not sure what word is used in the Prusa community. I mean going through the process of tweaking this and that to improve the reliability. There is data in support of the mmu2 being a great addition, but at the moment I have a user interaction rate of about 5-7%. With 100 changes, I have to intervene on about 6 of them. – cmm Apr 22 '19 at 22:50
• @Mick Thanks for the reference to the Facebook group. I'm waiting for a moderator to approve my join request. – cmm Apr 23 '19 at 18:09
• Ah tweaking, now that's a word I can understand... gotcha :-) – Greenonline Apr 24 '19 at 18:01
